Efento NB-IoT sensors transmit data using the NB-IoT (Narrowband IoT) network and do not require any additional devices (router, gateway, etc.). The device is powered by two AA batteries, thanks to which the installation does not require running power and signal cables. The measurement period is configurable in the range of 1 minute 10 days. In addition, you can set the data transmission period to the Efento Cloud platform to extend the device’s battery life. The sensor allows configuration of alarm thresholds, exceeding of which will cause immediate data transmission to Efento Cloud, regardless of the configured transmission period.
The sensor is also equipped with a Bluetooth Low Energy interface that allows local data reading using a smartphone with the Efento Logger application and device configuration without connecting it to a computer or installing drivers! The device can also be configured remotely via Efento Cloud.
On request, each Efento sensor can be supplied with a calibration certificate in accordance with ISO / IEC 17025. The test is performed in an external measurement laboratory, using a laboratory thermometer calibrated with reference to the standards of the Central Office of Measures.
The sensors comply with European standards and directives and bear the CE mark.
